内容介绍

FnDLQdhMuYhKDB0JTy-VIX_UJZo0

简介

Wio Terminal的运行速度为 120MHz (最高可达200MHz), 4MB 外部闪存和 192KB RAM。

Wio Terminal自身配有一个2.4英寸 LCD屏幕, 板载IMU(LIS3DHTR)，麦克风，蜂鸣器，microSD卡槽，光传感器和940nm红外发射器。除了这些它还有两个用于Grove生态系统的多功能Grove接口和兼容Raspberry pi的40个GPIO引脚，用于支持更多附加组件。

任务内容

任务二：
制作一个自动联网的天气预报仪，在设计界面显示温湿度、天气情况、空气质量以及未来三天内的天气变化

实现原理

首先先去心知天气注册一个账号

FsfLslE-qBsaexhBJLH2dvRXCO6c

然后在控制台申请一个免费平台。试用版也行。

FglZm1FnnzsbhVsEMJElDCtFojFW

然后将密钥复制。

FoipdiwW8QGwmRBKJbIdzpnL9vqd

在Arduino里面填入密钥，就可以通过网络获取天气了。

代码

通过代码配置，初始化串口，WiFi，屏幕，定时器，之后连接心知天气的服务器，获取未来3天的温度和空气质量，获得数据后会关闭WiFi。当定时器计数到一定的时间之后，会再一次联网获取数据。
